An article published in the journal “Nature Physics” describes an analysis of the data collected by ESA’s Venus Express space probe during the final phase of its mission. After about eight years orbiting the planet Venus, in 2014 it was sent down lower and lower into the atmosphere, where it collected many new data before ending up getting destroyed. This allowed for example to discover the extraordinarily low temperatures of some atmospheric waves that have an average of about -157° Celsius (about -250° Fahrenheit).
NASA released new photos of various craters on the dwarf planet Ceres taken from its Dawn space probe, currently in its lowest orbit at an altitude of 385 kilometers (240 miles). From there, Dawn is making the most detailed mapping of Ceres and is providing really interesting details of craters that had already attracted the attention of scientists such as Haulani and Oxo.
An article published in the journal “Nature” describes a research that made it possible to map the climate on the exoplanet 55 Cancri e. It’s a planet already well known for the many studies carried out in recent years, in this case the Spitzer Space Telescope was used to try to get a better idea of the existing temperatures on the surface of this super-Earth. They can reach extreme levels, estimated between 1,400 and 2,700 Kelvin.
An article published in “Astrophysical Journal Letters” describes a research on a forming protoplanet in the TW Hydrae star system. By using the ALMA radio telescope, a team led by Sean Andrews of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, obtained the best image of a protoplanetary disk produced so far.
At the 47th Lunar and Planetary Science Conference held last week in The Woodlands, Texas, new results were presented of the analyzes of data collected about the dwarf planet Ceres by NASA’s Dawn space probe. Some of the mission scientists presented a new color map of Ceres surface and new highly detailed pictures of Occator crater, famous for the presence of the largest among the white spots, but also other interesting craters, especially Oxo, where water was found.
